Illustrative components of the geological environment

In this chapter we provide an account of the contribution made by the Geosphere, in
particular bedrock geological materials (part of the lithosphere), groundwater and
hydrochemistry to the development of a GDF. In order to put this in context we provide a
brief account of the general requirements of these attributes, particularly in respect of the post
closure safety and, to a lesser extent, the construction phase of the GDF. We also provide a
brief summary of the international approach to using bedrock geological materials and go on
to describe the summary properties from a range of bedrock geological materials (lithologies
and formations) in England, Wales and Northern Ireland, illustrated from well-documented
examples.
